[wakelock] Add module for virtual wakelocks. Contributes to JB#32462

MCE has multitude of reasons for blocking late suspend. Using real
wakelocks for each reason pollutes the kernel bookkeeping data and
using dynamically named wakelocks would make things even worse.

Add mce-wakelock module that multiplexes virtual wakelocks internal
to mce into just one real sysfs based wakelock.
